Missing backingstore / Window Refresh on linux, X11 Xorg-Server 1.20.1-r1
I have some problems with openbook-desktop v0.0.43-2.
Expected behavior: After any part of the openbook-desktop window was behind any other GUI element or outsdide of the active viewport, openbook-desktop should repaint it's contents.
Found behavior: Contens of the window will not refresh itself. One need to actually scroll or move the content in any other way to get a full refresh.
Exception: When a text-box for entry is open, openbook-desktop does automatic refresh.
